Answer:
There is a 38% chance at least 1 was blue
Step-by-step explanation:
there are 8 marbles total 3 being blue. 3/8= .375 = 38%
The probability of getting at least 1 blue marble in the given situation is 0.375, i.e., 37.5%.
Probability is the ratio of favorable outcomes to the total number of outcomes.
It is given that there are 3 blue and 5 red marbles in the bag.
Therefore, the total number of marbles in the bag is 8.
Let's take two scenarios, one when one blue marble and one red marble are drawn and the second one when both marbles drawn are blue.
Let B and R be the events of drawing a blue marble and red marble, respectively.
Case 1:
The probability of getting one blue and one red marble is calculated as follows:
[tex]P(B =1, R=1) = \dfrac{3}{8}\times\dfrac{5}{7}[/tex]
[tex]= \dfrac{15}{56}[/tex]
Note that the replacement is prohibited.
Case 2:
The probability of getting two blue marbles is calculated as follows:
[tex]P(B =2) = \dfrac{3}{8}\times\dfrac{2}{7}[/tex]
[tex]= \dfrac{6}{56}[/tex]
The probability of getting at least 1 blue marble is given as follows:
[tex]P(B\ge1) = P(B =1, R=1) + P(B =2)[/tex]
[tex]= \dfrac{15}{56}+ \dfrac{6}{56}\\= \dfrac{21}{56}\\=\dfrac{3}{8}\\= 0.375[/tex]
Therefore, the probability of getting at least a blue marble is 0.375.

Can you find the perimeter of each rectangle and type the correct code? Please remember to type in ALL CAPS with no spaces. *
Answer:
CEFA
Step-by-step explanation:
The perimeter of a rectangle is the sum of the lengths of the 4 sides. A rectangle has two lengths of equal size and two width of equal size. To find the perimeter, add the length and width and multiply by 2.
1. perimeter = 2(3x + 2 + 2x) = 2(5x + 2) = 10x + 4
2. perimeter = 2(4x + 1 + x) = 2(5x + 1) = 10x + 2
3. perimeter = 2(x + 5 + 7) = 2(x + 12) = 2x + 24

A conjecture and the paragraph proof used to prove the conjecture are shown.
GIVEN: ABCD is a parallelogram
DC bisects ∠BDE
PROVE: ∠1 ≅ ∠3
Drag an expression or phrase to each box to complete the proof.
Answer:
Please see below :)
Step-by-step explanation:
Angle 2 is congruent to angle 3 by definition of angle bisector.
Angle 1 is congruent to angle 3 by the transitive property of congruence.
Please let me know if something's wrong!
The missing values are:
<2 = 1/2 ∠BDE by Angle Bisector Theorem.
<3 = 1/2 ∠BDE by the transitive property
It is given that ABCD is a parallelogram, so AB || DC by the definition of parallelogram.
So, <1 and <2 are corresponding angles.
Therefore, <1 ≅ <2 by the Corresponding Angles Theorem.
It is also given that DC bisects ∠BDE,
So <2 is half the measure of ∠BDE by the Angle Bisector Theorem. Therefore, <2 = 1/2 ∠BDE.
Therefore, <3 is also half the measure of ∠BDE by the Transitive Property. Thus, <3 = 1/2 ∠BDE.
Therefore, <1 ≅ <3 by the transitive property of congruence.

Gabrielle is 11 years younger than Mikhail. The sum of their ages is 77 What is Mikhail's age?
Answer:
44
Step-by-step explanation:
The relations can be written using one variable to represent Mikhail's age: m. Gabrielle's age is (m-11), so the sum of their ages is ...
m +(m -11) = 77
2m = 88 . . . . . . add 11
m = 44 . . . . . . . divide by 2
Mikhail's age is 44.
__
Additional comment
Gabrielle is 33.
You could solve this using two variables:
m - g = 11m + g = 77Adding these two equations gives the one we have above:
2m = 88
m = 44
__
You may have noticed we are given the sum and the difference of the two ages. The older Mikhail's age is half the sum of those two numbers. The younger Gabrielle's age is half their difference: (77 -11)/2 = 33. This "half the sum, half the difference" solution is the generic solution to a "sum and difference" problem.
Gabrielle : 33
Mikhail : 44
Explanation:
Let Mikhail's age be x
And Gabrielle's age be y.
======================
Gabrielle is 11 years younger than Mikhail
y = x - 11 [ equation 1 ]
sum of their ages is 77
x + y = 77 [ equation 2 ]
Insert equation 1 into 2
x + x - 11 = 77
2x = 77 + 11
2x = 88
x = 44
Therefore, the age of Mikhail is 44
Find Gabrielle's age:
y = x - 11
y = 44 - 11
y = 33
Therefore, the age of Gabrielle is 33

An isosceles triangle has a perimeter of 28cm and sides of integer length.
How many different such triangles can be made?
Answer:
over 18716271717161626cm
To solve this question, we have to:
Understand the concept of an isosceles triangle.Understand the perimeter concept.Understand the constraint needed to represent a triangle.Doing this, we get that: 6 different such triangles can be made.
Isosceles triangle:
In an isosceles triangle, two sides have the same measure. An example is given by the picture at the end of this answer.
Perimeter:
The perimeter of a polygon, in this case a triangle, is the sum of all it's sides.
Constraint:
The sum of the lengths of the two smaller sides of a triangle has to be greater than the length of the greater side.
This triangle:
Perimeter of 28.Two sides of x.One side yThus, the perimeter is:
[tex]P = 2x + y = 28[/tex]
Now, for the values of x, we find if the values of y generate a triangle, respecting the constraint.
x = 1
[tex]2 + y = 28 \rigtharrow y = 26[/tex]
1 + 1 < 26, thus, the constraint is not respected.
x = 2
[tex]4 + y = 28 \rightarrow y = 24[/tex]
2 + 2 < 24, thus, the constraint is not respected.
x = 3
[tex]6 + y = 28 \rightarrow y = 22[/tex]
3 + 3 < 22, thus, the constraint is not respected.
x = 4
[tex]8 + y = 28 \rightarrow y = 20[/tex]
4 + 4 < 20, thus, the constraint is not respected.
x = 5
[tex]10 + y = 28 \rightarrow y = 18[/tex]
5 + 5 < 18, thus, the constraint is not respected.
x = 6
[tex]12 + y = 28 \rightarrow y = 16[/tex]
6 + 6 < 16, thus, the constraint is not respected.
x = 7
[tex]14 + y = 28 \rightarrow y = 14[/tex]
7 + 7 = 14, thus, the constraint is not respected.
x = 8
[tex]16 + y = 28 \rightarrow y = 12[/tex]
8 + 8 > 12, thus, the constraint is respected, and this is the first possible triangle.
x = 9
[tex]18 + y = 28 \rightarrow y = 10[/tex]
9 + 9 > 10, thus, the constraint is respected, and this is the second possible triangle.
x = 10
[tex]20 + y = 28 \rightarrow y = 8[/tex]
8 + 10 > 10, the constraint is respected, and this is the third possible triangle.
x = 11
[tex]22 + y = 28 \rightarrow y = 6[/tex]
11 + 6 > 11, the constraint is respected, and this is the fourth possible triangle.
x = 12
[tex]24 + y = 28 \rightarrow y = 4[/tex]
4 + 12 > 12, the constraint is respected, and this is the fifth possible triangle.
x = 13
[tex]26 + y = 28 \rightarrow y = 2[/tex]
13 + 2 > 13, the constraint is respected, and this is the sixth possible triangle.
x = 14
[tex]28 + y = 28 \rightarrow y = 0[/tex]
Cannot have a triangle with a side of 0, so this is not possible.
After the tests, we have that 6 different such triangles can be made.

Answer:
Graph (C)
Step-by-step explanation:
To find whether the graph\table represents a relationship or a function we have to analyze the input-output values given.
Graph A.
In this graph for every input value (x-value) there are two output values (y-values).
For x = -2, y = -2, 2
So the graph doesn't represent a function.
Graph B.
For every x value there are two y-values
For x = -5, y = -3, 3
So the graph doesn't represent a function.
Graph C.
For every input value there is a different y-value.
Therefore, graph represents a function.
Graph D.
In this graph for x = 3, y = 1, 2, 3, 4
For one value of x, there are four values of y.
Therefore, graph doesn't show the relationship.
Graph C has exactly one output (y-value) corresponding to each input (x-value), therefore, the graph that represents a functional relationship is: Graph C.
What is a Functional Relationship?A functional relationship is a relationship whereby every input in the relation has exactly one possible output.
In other words, a functional relationship must have exactly one output that corresponds to each of the input values.
Thus, graph C has exactly one output (y-value) corresponding to each input (x-value), therefore, the graph that represents a functional relationship is: Graph C.

a map has a scale of 1/2 inches:12 miles if the actual distance between the cities is 480 miles how far apart are they on the map
Answer:
20 inches
Step-by-step explanation:
Since there are 480 miles in total, we have to divide it by 12 so we can see how many half inches that would be.
480÷12 = 40
That would mean you can fit forty 12's in 480. Since 12 miles equals 1/2, you would multiply it by 40.
1/2 × 40 =20
This means that the distance between the cities on the map would be 20 inches.

Step-by-step explanation:
To figure this out we can write a really simple equation! to start we're going to identify our variables: in this case we'll make [tex]T[/tex] for total, [tex]c[/tex] for the amount of copper, [tex]a[/tex] for the amount of aluminum, and [tex]p[/tex] for the amount of plastic. We can then create this equation to represent the sum of the amount of material times the value. This equation will look like this: [tex]T=1.48c+1.55a +.30p[/tex]
Now that we have an equation written out, we can plug in the amount of each material to get [tex]T=1.48(50)+1.55(15)+.30(10)[/tex]. We can then simplify this by following PEDMAS and multiplying to get [tex]T=74+23.25+3[/tex] and then all we have left is to add to get [tex]T=100.25[/tex]

what is the are of triangle ABC with vertices A(-2,1),B(-2,3),C(2,1)?
Answer:
A. 4 square units
Step-by-step explanation:
The area of a triangle is given by the formula ...
A = 1/2bh
Your triangle has a base of 4 units and a height of 2 units. Its area is ...
A = 1/2(4)(2) = 4 . . . . square units
__
The triangle dimensions are easily found from your diagram by counting grid squares. If you like, you can subtract the x-coordinates of the points on the horizontal line y=1 to find the base length: 2 -(-2) = 4. And you can subtract the y-coordinates of the points on the vertical line x=-2 to find the height: 3 -1 = 2.
